Contraceptive device designed for mexican women according to the dimensions of their uterine cavity acoording to their parity

Abstract

The present invention relates to a flexible plastic intrauterine device with contraceptive aim, which has a “T” shape. The length of the horizontal arms coincides approximately with the width of the uterine bottom according to the parity and the length of the vertical rod of the frame with the functional uterine cavity of the nulligest, nulliparous, young and multiparous Mexican women. The intrauterine device is presented in five models whose measurements of length of the frame or of the tilde or horizontal arms are from 13 to 33 mm and the length of the post or vertical rod is from 21 mm to 39 mm. Attached or injected thereto is included a plastic monofilament from 10 to 40 cm in length in the distal end of the post or vertical rod whose shape is a spherical, hexagonal or flat. The plastic frame of medical grade contains wound in the tilde or both horizontal arms of the “T” a copper filament from 0.24 to 0.26 mm in diameter or a copper tube from 2.1 to 2.2 mm in exterior diameter, and a length of 4.9 to 5.2 mm that is 99.99% pure. Furthermore in the post or vertical rod there will also be a winding of copper filament between 0.24 to 0.26 mm in diameter, whose total surface, of the horizontal arms and of the post or vertical rod is between 200 and 380 mm2. Plastic frame of radiopacifiant material of 23%±5% and 77%±5% of flexible medical plastic grade and viscoelastic or deformation properties not greater than 5 mm of its original form.

Description

RELATED U.S. APPLICATION[0001]This application is a continuation-in-part of Ser. No. 10 / 580,328 filed May 24, 2006, entitled “METHOD FOR THE PRODUCTION AND POSITIONING OF AN INTRAUTERINE DEVICE WHICH IS ADAPTED TO THE UTERINE CAVITY MEASUREMENTS,” pending, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention has the fundamental intention to substantially diminish the collateral effects, mainly bleeding and pain, of contraceptives which are constituted by a plastic frame in form of a T and medical grade copper, by means of its adaptation to the measurements of the uterine cavity of Mexican women.BACKGROUND OF THE INVENTION[0003]In the decade of the Sixties and early Seventies, a signal arose as world-wide alarm, produced by the population increase that threatened to overflow the natural reproductive limits that during thousands of years humanity had enjoyed. This phenomenon was located, mainly, in the developing countries thereby incr...

They were too large.

On the other hand there have been cases of pelvic infection (“PID” by its abbreviation in English) associated to the presence of the IUD which, if not taken care of adequately, may cause infertility.
